Abstract: | Electrochemical biosensors are particularly suitable for miniaturization and integration in microfluidic devices. Applications include the detection of whole cells, cell components, proteins, and small molecules to address tasks in the fields of diagnostics and food and environmental control. Microfluidic setups range from simple channels for sample transport to channels with integrated sensing electrodes to highly sophisticated platforms with additional elements for sample preparation. The design of the microfluidics depends on both the type of detection and on the application and sample material. This review summarizes recent work on electrochemical biosensors with integrated microfluidics with the focus on developments for real sample applications, particularly those including measurements with real sample media. |
